12.1 cubes at 34 hz. alphas should be here in a good 2 weeks. whole box was constructed of 3/4" 7 layer birch. double baffle on top. i also used quarter round on all the seems inside of the box so i have no 90 degree angles.
birch=free had two sheets lying around at my dads, a couple edges had been rounded already but since i completely sealed off the enclosure from the inside and wood filler + glue on the outside it shouldnt be a problem. just a cosmetic hinderance. the ports are 3 x 5 and i used the PSP port calulator, after displacements, it came out to 34 hz so hopefully thats right
for that much space i would do min 2-6" aero's or 4 - 4" you can tune a lil higher with the aero's than you would with a slot port since they are more effiecent.
but other than the lacking port area it looks good.
thanks cal. but no the land rover does have to go. i am seriously having a hard time feeding my terrible car audio addiction while paying 70 bucks to fill up on a 6 75 an hr wage, its tuff. but yeah after working wtih this birch MDF seems like fisherprice toys. i will look into adding more ports. what i did with the double baffle was use tightbond on the top layer mount the baffles flush, clamp the baffles really tight for about a half hr and also shot about 8 very tiny nails with a brad nailor.
well the guys above aid it right - needs more port area , @ least 10sq"\cuft is a good rule
but looks nice
liked how u braced it - reminds me of a recnt box i did which was about 2cuft under volumed & i used 2 pieces of 2x4 to brace it = solid like a rock & vibration free too .....
